> The "undefined" property type is only allowed in property definitions.  According to the JSR-170 specification (Section, 6.2.5):
>     "This constant can be used within a property definition (see 6.7.6 Property Definitions) to specify that the property in 
>     question may be of any type. However, it cannot be the actual type of any property instance. For example it will 
>     never be returned by Property.getType and (in level 2 implementations) it cannot be assigned as the type when 
>     creating a new property."
> When the property definition has a type of "undefined", then we'll need to choose what actual type to use.  There doesn't appear to be any guidance on this in the spec (anybody?), so barring that the most logical approach is probably to look at the first property value.  
> Note that this is one reason why the DNA graph API was designed with the value factories to allow (or encourage) the client to convert the property values to the type desired by the client.  Because of this, it doesn't matter so much what type the value actually is, but rather that it can be converted to the type needed by the user.  So this should make the above assumption (about choosing the property type based upon value) a pretty decent one.
